Lumetri causing multicam clip to turn black

I am currently editing a multiple camera sit-down interviews on a 4K sequence. I am using the multi-cam workflow to edit this project.

Within the multicam sequence I have four tracks of video. All the clips are RED footage. I changed each individual clips Master RED color to set balance and match the cameras as best as possible and then used lumetri on each clip to match further and add some style. I then edited the multicam sequence within my edit sequence.

I noticed that one of the clips was slightly discolored(the light changed slightly in the room) so in my edit sequence, I jumped over to color to make an adjustment. As soon as I made a change to the Lumetri effect the clip went black. It does not appear in the program monitor. That clip DOES have a cross dissolve on it, and that portion of the clip appears in the program monitor. Once the clip goes black there is no way to get it to appear again. The only solution I've found is to remove the lumetri effect from it and then close and reopen Premiere.

I also noticed this effect on any nested clips. I had to stabilize a shot, so I nested the clip got it stabilized and when I tried to color that nested sequence in the edit...the clip goes black.

After further investigation I found that if I go back into the multicam sequence (Reveal in Project > Open in Timeline) and make a change to the lumetri effect on the cameras clip, when I return to the edit sequence the clip is no longer black and I can make a change to the lumetri with no problem. If I make more than one or two changes the clip goes black again and the only way to get it back is to repeat that process of going into the multicam sequence and making a change to the lumetri effect.

I know that there are multiple effects on the clip which is probably the issue...but I've done this time and again before, and am just now running into this problem. Any advice on what the solution may be, or is this just a bug?
